    Subject: Skype users?
    From: "Jack T. Textor" <jtextor@thepalmergroup.com>
    Are there any Pieter's out there using Skype (voice over Internet)? Was wondering if there would be any interest for a weekly or monthly conference call to assist other builders. I discovered it last weekend and it's pretty neat stuff and free! Jack Textor Des Moines

    I used my great-grandfather's draw knife for shaping the landing gear struts for my Piet. My dad gave it to me about a year ago -- I noticed it has 1836 stamped/engraved in the blade. It is in excellent condition although obviously used quite a bit. While working with it I wondered what g-grampa would think about building an airplane! And I wondered what he would think about airplanes period! Was very satisfying to use that tool. Anyway, a good sharp draw knife works very nicely, even on white ash landing gear struts -- practice on some scrap lumber -- you have to be aware of the direction of the grain and you must have your work secured tightly. Be very careful! While I was working on the elevators last night I was thinking that another tool that I consider indispensable is a good shop vac. You have to keep your work area clean -- and you do not want sawdust getting into glue joints. I use my vac every time I'm getting ready to glue parts together -- I literally vacuum the pieces to make sure there's no dust on the surfaces. Fred B. La Crosse, WI

    --> Pietenpol-List message posted by: Michael D Cuy <Michael.D.Cuy@grc.nasa.gov> Cliff--your web pages are just great and I enjoyed seeing how you developed your teardrop/streamlined shape on your wood landing gear legs. Excellent workmanship from what you show in your photos as well along with the personal touches of the leather stick grips and rudder bar wraps. Gives a new meaning to the word wrap. I really enjoy seeing the new generation of Pietenpol builders and how every successive few batches of planes have better workmanship and more innovative ideas. Looks great, less filling.

Make some test pieces out of scrap, let the glue cure and then break it. I did, and all cases the wood broke not the glue joint. I used T 88 epoxy. It is great confidence builder. Keep building Hans

    Subject: Gussets and Sanding
    From: "Bill Church" <eng@canadianrogers.com>
    --> Pietenpol-List message posted by: "Bill Church" <eng@canadianrogers.com> Glenn, I think what you want to avoid are two things: 1. Sawdust on the surface of the wood being bonded, which has the potential to reduce the strength of the bond. 2. Glazed wood surface caused by sanding with worn-out fine sandpaper. Wood in the as-sawn (or planed) condition is excellent for bonding, but if two surfaces are uneven sometimes a bit of sanding is necessary to level the playing field. In those situations, use a medium to coarse sandpaper, and as you say, wipe with a tack rag or mineral spirits (same thing). One other thing to do in your preparation for glue-up is to sand the face of the plywood that will be bonded (using a medium grit sandpaper). I used a cross-the-grain sanding direction for maximum scratch-up potential. The manufacturing process for plywood uses heat and pressure, which results in a sort of glaze on the face of the plywood, which inhibits absorption of the glue into the fibers of the plywood. Of course, it's much easier to sand the entire back side of the sheet of plywood before you cut it into hundreds and hundreds of little tiny hard to handle gussets. Or you could do what I did, and cut out all those hundreds of tiny little gussets before sanding the back of the sheet, even though you knew that you were supposed to sand the %$#&@* back of the $#%&@ plywood!

    --> Pietenpol-List message posted by: Galen Hutcheson <wacopitts@yahoo.com> I sanded my joints and in all of test pieces, the wood broke and not the glue/wood interface. I tested them against joints that had been sawn and not sanded and found that they all broke about the same. I used T-88 glue and all the test pieces were subjected to the same evironmental conditions. Others may have found different results, so take this for what it is worth.

    From: "Glenn Thomas" <glennthomas@flyingwood.com>
    --> Pietenpol-List message posted by: "Glenn Thomas" <glennthomas@flyingwood.com> Good info. I wondered about the gussets too. They get handled quite a bit during the cutting and edge-sanding process and thought they could benefit from cleaning/roughening due to their smoothness and picking up oils from skin during handling. I think I'll break a couple to see how they hold up. That IS a good confidence builder. The build and break approach should teach me something about strength. I noticed (building models) that if you apply too much force with the tack rag that stickiness from the rag can end up on the surface you're cleaning. I've used mineral spirits on a hardwood floor I put in and it didn't seem to leave anything behind and you could see traces of sawdust on the rag even though the floor seemed clean to the naked eye and to the touch. Was curious if mineral spirits completely evaporates or leaves any kind of oil behind.

    Subject: a test for glue joints and sanding
    --> Pietenpol-List message posted by: Michael D Cuy <Michael.D.Cuy@grc.nasa.gov> Glenn-- I sanded nearly 100% of my glue joints--generally a rougher paper too and then just blew or vacummed off the dust before gluing with T-88. After 450 hours of flying no joint that I'm aware of has come undone. Whatever method you use just do some test pieces now and then (the astute FAA inspector or DAR might ask to see some test pieces during your inspection) by gluing some spruce to plywood with some ply overlapping by an inch or two then smash in a vise. If the wood fails your glue joints are just fine. (this works for any type of wood glued to any other or same kind of wood) Mike C.

    Subject: aluminum-to-aluminum gluing with T-88
    As a side note, I found that if you need to glue alum. sheet to alum sheet. that if you sand the glue surfaces with 80 or 100 grit, clean with a solvent and glue, you get a fantastic glue joint. When I bent up my Lexan windshields (bowed them into position) and secured them to my three brackets they distorted the 2024-T3 aluminum instrument panel covers !!! I removed the windshields and glued three discs of aluminum sheet (about 2.5" dia) to the underside of the curved alum. cockpit/inst. panel covers, let cure and wha-la, no more distortion of the surface when I re-attached the windshields. This saved some riveting where I normally would have had some unwanted rivets. Mike C.

What do you think would be the cost/value of a clean A-65 with a couple of hundred hours SMOH, good compression, newer Slick mags and harnesses, Stromberg carb, exhaust stacks, wood prop, and hub? Not the one on 41CC; this is another engine that is for sale, well stored, taken off a flying Champ, and I'm wondering what it might be worth. Thanks for any ideas.

    --> Pietenpol-List message posted by: "Phillips, Jack" <Jack.Phillips@cardinal.com> Good question, Oscar. Just looking at the accessories that go along with this engine, if you had to buy them separately, the costs would be something like: Magnetos $800 Prop Hub $500 Propeller $1,200 (assuming certified, since it came off a Champ) Exhaust stacks $400 You're up to close to $3,000 right there I paid $1500 for my A65 as a run-out core, and then put another $5500 in new parts into it. I ended up with a zero SMOH engine with new cylinders, pistons, camshaft, magnetos, valve lifters, an overhauled crankshaft and gears, and an overhauled crankcase. Total price $7,000 so that should probably be your top-end price. That price did NOT include the prop or the prop hub, or the exhaust system.

    Subject: Re: Gussets and Sanding
    --> Pietenpol-List message posted by: "Catdesign" <catdesign@intergate.com> I've used both birch and Mahogany plywood and I feel there is no need to sand either, especially the Mahogany. If there was a glazed surface, ive necer seen one on anything thicker then 1/32 ply,I would scuff it very very lightly with 150 sandpaper. I recall reading an article about testing sanded joints vs. non-sanded joints in plywood. But I cant find this article. Anyone else remember this? All my test samples on glued plywood the wood ripped in half. Not the T-88 glue joint. I sand my spruce joints with 50 to 80 grit sandpaper then vacuumed the joint to suck out any dust. T-88 Glue samples tested to destruction have proved this method to fail the wood not the glue joint. I think sanding with fine sandpaper is the problem. Epoxy by nature needs some tooth to grab hold of and does not penetrate deeply into the pores. Remember epoxy can glue metal to metal, as long as it has some tooth to grab hold of.

    Hi Mike I just want to add to your windshield point. If you have a large enough oven and an understanding wife, you can heat the lexan and bend it to shape. Heat at about 250 F for about 10-15 min and it becomes soft. Lay it on template the shape of your bridge deck and let cool. Of course, run test pieces for time and lay piece on good, clean, flat surface while baking. I didn't notice much smell.

    Hi The Gougeon book on boat construction "West Epoxy Guys" recommends sanding the aluminium while it is covered with epoxy as a final step to bond aluminium fittings to wood. I understand this doesn't happen in a Pietenpol but it tells you how quick the metal can oxide. It is a great book with a lot of information on epoxy and various additives. There is also a full chapter on safety.

What am I doing wrong? ;o) Seriously, the guys over on the KR list (where a full canopy is usually involved) tend to shy away from oven-forming this stuff and try to go with factory canopies. We actually have it pretty easy with the small windscreens that are typical on Piets. 41CC has nice curved windscreens but the 3-piece segmented flat ones do seem a trifle more "antique", if not a heck of a lot more trouble to make the frames and all.
